Tub Drains are designed to be installed during a new bathtub installation, and help to drain the water safely out of the tub and into the sewage line. Tub drains can include the strainer piece, a grid drains, a push drains to help and catch and non-liquids from entering the drain. Many Shower & Tub Drains come with the optional feature of having a coordinating overflow plate to match the finish of the tub spout while providing safety by not letting the tub overflow. Consider tub drains from Kohler, Sterling, Morn and American Standard.
